A member of the health care team is researching the etiology and pathogenesis of a number of clients who are under his care in a
hospital context. Which of the following aspects of clients' situations best characterizes pathogenesis rather than etiology?A. A client who has been exposed to the Mycobacterium tuberculosis bacteriumB. A client who has increasing serum ammonia levels due to liver cirrhosisC. A client who was admitted with the effects of methyl alcohol poisoningD. A client with multiple skeletal injuries secondary to a motor vehicle accident
The correct answer is B. A client who has increasing serum ammonia levels due to liver cirrhosis
Explanation:
Etiology is the study of origin or cause of any disease. Pathogenesis is the mechanism of causing disease by any pathogen. Pathogens use four-step to become pathogenic which are contact, colonization, invasion, and infection.
In pathogenesis the symptoms of disease is observed not the cause so in option B increasing serum ammonia level is the symptom of liver cirrhosis which characterize pathogenesis rather than etiology and in other option, only cause of a medical condition is described so the correct answer is B.
Oxygen makes up another 20 to 21 percent of our atmosphere. It's essential for life on Earth, and interestingly enough, it is poisonous when highly concentrated. Our concentration of 20 to 21 percent seems just right.
